Similar to other known species in the genus, differing in the following characters. Body color: entirely dark brown except for brownish-yellow apex of frontal shelf. Frontal shelf: margined by 13-14 rounded teeth in female, ten in male. Median longitudinal furrow on vertex: weak, incomplete, visible only near occipital carina. Sculpture of vertex: rugose-reticulate, with superimposed coriaceous microsculpture. OOL: slightly less than ocellar diameter. Outer margin of mandible: with five to six teeth. Sculpture of mesoscutum: coriaceous, with longitudinal striae present only near transscutal articulation. Sculpture of mesoscutellum: rugose, with superimposed coriaceous microsculpture. Notauli: present only in posterior half of mesoscutum. Metascutellum shape: roughly triangular. Mesopleural carina: distinct, complete. Plicae on propodeum: well-developed. Felt field: present on S2.

The specific epithet refers to the cerrado habitat in which the specimens were collected and is treated as an adjective.


Since the original description of T. genieri   several additional specimens have been collected in the Brazilian state of Espírito Santo in or near the Sooretama Biological Reserve, the same area from which the species was described originally. The habitats are described on the specimen labels as semi-deciduous or primary lowland Atlantic forest. The additional species in the Center-West of Brazil, Paraguay, and Colombia suggests that the genus is very widely distributed and rare or perhaps restricted in its habitat preferences or timing of adult emergence.
